Rsync - Preserve owner/group with different UID/GID
Dear Folks :-) I want to rsync some files between some servers and preserve files owner and group (not UID or GID), in some machines UID and GID are differents, for example: a) In the rsync server: Code:
# stat vbseo.php File: `vbseo.php' Size: 26758 Blocks: 56 IO Block: 4096 regular file Device: 804h/2052d Inode: 21971712 Links: 1 Access: (0644/-rw-r--r--) Uid: (10002/ user1) Gid: (10001/ psacln) Access: 2006-10-09 18:30:59.000000000 +0200 Modify: 2006-10-09 19:12:48.000000000 +0200 Change: 2006-10-09 19:12:48.000000000 +0200 # grep psacln /etc/group psacln:x:10001: b) In the rsync clients: Code:
# stat vbseo.php File: `vbseo.php' Size: 26758 Blocks: 56 IO Block: 4096 regular file Device: 803h/2051d Inode: 37421492 Links: 1 Access: (0644/-rw-r--r--) Uid: (10002/ user1) Gid: (10001/ UNKNOWN) Access: 2007-11-30 10:46:59.000000000 +0100 Modify: 2006-10-09 19:12:48.000000000 +0200 Change: 2007-11-30 10:46:59.000000000 +0100 # grep psacln /etc/group psacln:x:2524: In the case of UID/GID are the same between machines there isn't problems.. but when don't match there are problems. I have tried several rsync options like "--owner", "--group", "--numeric-ids", "--super", etc.. but getting the same result.. is there anyway to make this with rsync? I have a similar solution with tar+ssh but I want to use Rsync: Code:
tar cpzf - /source --ignore-failed-read --ignore-zeros | ssh root@192.168.x.x -p22 "cd /destination; tar --same-owner -xzf -" Regards, -- Santi Saez |

The mapping of username to UID (and groupname to GID) stays within the server. The only way to get the names in sync is to keep the UIDs in sync or to chown the files after doing the copy sorry.
